WATER-CLOSET.

339,480, dated April 6, 1886.

(No model.)

securely closing, when not required to be open,

drain-pipes at or near their connections with water-closet pans, wash-bowls sinks, bathtubs, or other similar fixtures.

It consists in a combination, with the discharge-pipe of such fixture,water-closet, or

wash-bowl, &c., and the connecting drain, waste-water or soil pipe, andwith a plug or stopper trap valve, which with its box and seat is placedimmediately below the end of said discharge-pipe and above or in thecorn mencement of said soil or waste-water pipe, joining the two andforming their continuation, of an auxiliary or independent S-shapedpipe, trap-overflow arranged to connect said discharge-pipe from itsupper surface just before it terminates in the trap-casing with thecontinuing drain or soil pipe below the site of thestopper-valve, saidS,additional, and overflow pipe having also combined in its course aself-closing valve, so placed that it shall be opened by pressure ofoverflowing water from above, but only more tightly closed by pressureof gases rising from below, whereby, first, the contents of saidwatercloset, basin, or other 3 5 fixture is allowed to discharge whensaid stopper or plug valve is elevated by lifting upon its handle, andwash-water is at the same time and by the same movement allowed orcaused to pass through; second, the stopper or plug valve, when notpurposely elevated, shall remain seated to prevent an upward escape ofsewer gases or soilpipe emanations, and whereby, third, when such plugor stopper valve is closed provision is made through the auxiliary andadditional 8 and trapped connecting'pipe for the safe and easy escape ofwater which may from any imperfection of apparatus or otherwise beallowed to run into the connecting basin, sink, bath-tub, or otherreceptacle, and for the prevention of damage by overflow.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which the figure represents a partly sectionalview in elevation of a water-closet bowl or basin with my inventionapplied.

A indicates the waste, drain, or soil pipe with which the dischargepipeB from the basin or bowl 0 of a water-closet connects, and which initself comprises an S-trap, b, be tween such connection and the sewer ormain and soil pipe with which the drain-pipe connects and is continuous.

D is a plug or stopper valve, of a plunger or any other suitableconstruction, arranged to close the wastepipe A at its commencementbelow the valve-casing, also below and beyond the termination of thedischarge-pipe B, and is capable of being operated from above thewatcr-closet seat by its stem and handle 0 or otherwise when it isrequired to open connection between the discharge-pipe B and the waste,soil, or water pipe below it. said valve to be operated automatically orat pleasure, with a substantial seal to shut out from the apartment orbuilding in which the water-closet or other water fixtures or structuresare situated sewer-gases and soil-pipe emanations. Furthermore, saidstopper or plug trap valve has or may have combined with its stem andits casing, or substantially the latter, and operating above the seat ofthe closet, a

, screw-cap or other locking device, E, for forcibly and permanently,when required, securing its more certain and firm closure. This, asshown in the drawing, is applied as noted to the stem of the valve abovethe water-closet seat, where it is readily accessible, and when set byscrewing it down upon a pin or collar, 8, placed low down upon the valvestem or rod in the drawing, but properly being high up on the stem andwithin the lock-cap E, serves to compress the valve-plug upon its seat,and retain it there indefinitely and as desired, for the purpose ofpreventing during such time all upward and outward escape of gases. Itis to be observed that this lock is detached and not an essentialfeature of the trap. It is an additional and convenient means for securing prevention against the entrance of sewergases and soil-pipeemanations at night, or during longer periods when the water convenienceis not in use, during. seasons when the house is unoccupied, and throughunused fixtures, bath tubs, water closets, and washbowls in upper andunused rooms in houses otherwise occupied, wherein other, and especiallywater-seal traps, soon evaporate away, and thehouse andits inmates areunconsciously subjected to the entrance and bad effects of these gases.In this detached but readily applied manner this look, it will beperceived, is of great value. On releasing the look, however, said valveD may be raised at pleasure to admit of matter passing from thedischargepipe B into the waste or soil pipe A. It will be noticed,however, in such an arrangement or combination of devices that when theplug or stopper trap valve D is closed orheld closed by application ofthe locking device there can be no automatic discharge from the basin orother receptacle situated above through the discharge-pipe Binto thewaste-pipe A. There might occasions occur by reason of some defectivecondition or action of the device for controlling the flow of wash-waterto the watercloset basin or pan, or on account of forgetting to turn offthe faucet to another fixture where this stopper-trap may be in useanddisconnected in its action from the action of the supply-faucets,that water should continue to flow into the receptacle, fill, andoverflow, and thereby cause damage from such overflowing; but to preventsuch retention and damage by water, and yet equally provide against theescape upward of sewer-gases and soil-pipe upper side of the valve-box 6connection is formed with the waste-pipe A by a pipe, d. Thecommencement of this overflow device is madefrom the upper surface ofthe dischargepipe B, in order that it may not catch and become filledwith solid matter passing through said pipe B; and, furthermore, so thatwater even should not pass through it until the discharge-pipe and basinare filled to a certain level in order to retain water in a pan, itturns and extends downward and then upward, in order to form awater-seal, and also to enter the box 6 from beneath, and thus actagainst and cause its valve 6 to open by upward pressure. Theconnecting-pipe d with the wastepipe A is given off from the upper partof the chamber formed by the valve-casing e above its valve 6', so thatany pressure of gases arising in the waste-pipe A from the sewers orsoil-pipes and entering the connecting-pipe d shall act upon the uppersurface of the valve 6'' to keep it even more tightly closed. The valvetrap or box 6, with its valve 6, is represented as a simplepoppet-valve, with'its valvestem free to slide upward in a screw-cap, f,on

the top or" the chamber which holds said valve,

so that the valve 6 may readily be removed when required by taking offthe screw-cap f. Thus this overflow attachment provides for an automaticand cflicient discharge and escape of running water on the one hand,while it equally, by its 3 shape and additional trap operated, asdescribed, provides against an upward escape of injurious gases on theother.

Having thus described my iuvention, what I claim as new, and desire tosecure by-Lett'ers Patent, is-

The overflou S-trap pipe G and its selfclosing valve 0', in combinationwiththe discharge-pipe B, the branch piped, drain-pipe A, with its plugor stopper trap valve capable of manipulation by hand, and the basin,pan, or receptacle 0, essentially as described.
